Remove four S20 episodes selected during manual video review: `episode_000007`, `episode_000011`, `episode_000015`, and `episode_000033`.
The change deletes all three camera views for each selected episode (12 MP4 files), removes their trajectory-index rows, and updates task metadata, the dataset manifest/checksum, and README counts. S20 retains 31 episodes / 93 videos, with 25 train and 6 validation samples. Dataset and split versions become 1.4.1.
Original episode numbers, all surviving train/validation assignments, and other tasks are preserved. Dataset totals become 1,007 trajectories (803 train / 204 validation) and 2,703 videos.
Validation: all 12 removed video hashes and sizes match the reviewed revision; all 93 retained S20 video references resolve with matching hashes; retained metadata rows and other task records are unchanged; JSON, counts, split membership, and the trajectory-index checksum are consistent.
Add State repeated-pouring anomaly S20 (35 trajectories)
Add the reviewed 2026-11-03 two-cup recovery demonstration: 35 unannotated real-robot trajectories and 105 frame-exact videos. Suite Order, task_variant recovery; 28 train / 7 val. Correct the exported instruction to two cups and retain the original recorded text. No stage or success labels are inferred. Preserve all 19 State tasks, existing files and frozen splits. Dataset/split v1.3.0: 20 tasks, 976 trajectories, 778 train / 198 val. No provenance directory is added.
Add S16–S19 from the 2026-11-03 PiperX collection: 137 unannotated trajectories and 411 frame-exact three-view videos. Exclude the reviewed tea #0/#1 and upside-down-cup #0 recordings; correct the bottle instruction to three bottles. Add 109 train / 28 val samples and preserve all existing S11–S15 files and frozen splits. Dataset/split v1.1.0: 9 tasks, 323 trajectories, 257 train / 66 val. No provenance files.
